User Reviews

Came stock on my Hardrock. Rode it hard for 1500 miles and--while it's not the smoothest shifting derailleur I've used--it was 100% reliable. I kept figuring I'd run it till it broke and replace it with a Shimano something or other, but the doggone thing never even came out of adjustment, much less broke!!!

Strengths: it looks good, shifts good and hasnt given me any bother in 6 months of raking the sh*t out of it. cheap.

i have it on my freeride bike and rake the balls of it and its running absolutely excellent! im very suprised at this because it has lasted longer than my shimano deore's that i had. id get it coz its cheap and has turned out to be very durable.

Bought this derailuer knowing I wasn't going to "shred" trails the way I used to, but wanted the SRAM quality... so far, it's been worth it. Shifts nice & quiet without any issues on the flat, up & down hills, over decently technical terrain and even chewed up a finger-sized stick and spat it out without so much as a hiccup.
Def worth the price if you're looking for a good, strong, reliable derailuer and you're not planning on racing or doing double diamond track on a regular basis. 5 flamin' turdies from me!!

Strengths: works as good as x5, x7
the x4 and x5 are stronger than the x7 due to the all steel "gear cage" thing, but not really that significant as far as performance. all have aluminum knucles that break easily

Weaknesses: any aluminum part breakes easily

Bottom Line:

The differances between the x4, x5, and x7 are nothing to brag about. The x4 works great when properly adusted and I could not tell the difference between any of them. They all break at any aluminum part, from sticks in my case, and none of them have replacable parts, except for bearing/gears which don't really break. The part that will break on these is the aluminum knucle that bolts onto the replacable derailer hanger. The differance between the x4 and the x5 is that the x4 has one plastic bearing and one metal, while the x5 and x7 have two metal bearings and the x5 and x7 have an extra part for chain/cog height adjustment, all of them seem to have a very subtle design change. I give it a 4 beacuse it broke, the third I've brook this season so I like'em cheap but I would like sram to come up with a design that doesn't catch sticks as well as these(x4, x5, x7, probobly x9 and x10 since the designs are near identical, all have the aluminum knucle)
